It turned out that this happened because I had an obsolete and
long-forgotten package installed which also shipped
/usr/share/man/man1/cpp.1.gz[1], and I had reinstalled cpp-doc with
"--force-overwrite" back then. Still, the md5sum of the replaced file
was still in place.

The problem can be reproduced with the attached dummy packages where a
regular file is replaced with a symlink (thus, there is no md5sum entry
for it in the replacing package).
